The celery bulbs must be harvested carefully and must be carried out first, if significant night frosts are to be feared.
The celery grows well into October, which has a favorable effect on the size of the tubers. That is why he is left on the beds as long as possible. You don't harvest it with a spade, but with the grave fork. The tubers must not be injured, because this easily creates rotten spots. The leaves are immediately removed except for 3 or 4 heart leaves.
